Background
David Scott Detrich was convicted of murder in Arizona and sentenced to death. His federal habeas petition — filed under 28 U.S.C. § 2254, the statute that governs federal court review of state criminal convictions — raised claims that his trial counsel provided constitutionally ineffective assistance (known as “IAC” claims, governed by Strickland v. Washington) during both the guilt and penalty phases of his trial. He also argued that the Arizona Supreme Court applied an unconstitutional test to mitigation evidence at sentencing.
After a series of proceedings spanning more than two decades, the case reached an eleven-judge en banc panel of the Ninth Circuit — the court’s largest type of hearing, reserved for cases of exceptional importance or to resolve circuit-level conflicts. The district court had denied habeas relief, and the en banc court took the case to address the proper standards for procedural default and the application of Martinez v. Ryan (2012), a Supreme Court case that created a narrow exception allowing federal courts to hear IAC claims that were not raised in state court if the failure resulted from the inadequacy of state postconviction counsel.
The Court’s Holding
The en banc court affirmed the denial of habeas relief across the board. On the threshold question of “fair presentation,” the court held that a claim is fairly presented to a state supreme court only when the circumstances as a whole fairly apprise that court that the petitioner is seeking some form of substantive or procedural relief on that specific claim. Merely including the underlying petition in the appendix of a state filing, without more, is insufficient to constitute fair presentation.
On procedural default and the Martinez exception, the court held that to establish “cause” to excuse default under Martinez, a habeas petitioner must demonstrate a reasonable probability that the outcome of state postconviction proceedings would have been different had counsel raised the IAC claims in that forum. Detrich failed to make this showing for most of his guilt-phase IAC claims. The one non-defaulted claim — that trial counsel was deficient in not retaining a forensic expert to challenge a prosecution witness’s testimony about gurgling sounds made by the victim — failed on the merits because the Arizona Supreme Court reasonably concluded that no prejudice resulted; overwhelming evidence supported the verdict independently of the challenged testimony. The Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA) therefore precluded relief because the state court’s conclusion was objectively reasonable.
Judge Nguyen concurred to clarify that Martinez is a specific application of Coleman v. Thompson’s cause-and-prejudice requirement for overcoming procedural default, not a separate standard that replaces Coleman’s actual prejudice requirement with a “substantiality” test.
Key Takeaways
- To “fairly present” a federal habeas claim to a state supreme court, a petitioner must do more than include the lower court petition in an appendix — the overall submission must affirmatively signal to the state high court that the petitioner is seeking relief on that specific claim.
- Under Martinez v. Ryan, to excuse a procedural default based on inadequate postconviction counsel, the habeas petitioner must show a reasonable probability that the state postconviction outcome would have been different had counsel raised the claims — a demanding showing that goes beyond merely demonstrating that the underlying IAC claim has merit.
- AEDPA’s highly deferential standard of review under 28 U.S.C. § 2254(d) means that even colorable IAC claims will fail on habeas review if the state court’s rejection of the prejudice argument was not objectively unreasonable — a very high bar.
- IAC claims at sentencing in capital cases must show both deficient performance and prejudice under Strickland; failing to present additional mitigation or challenge an aggravating factor does not warrant relief where the state court’s prejudice determination is objectively reasonable on the record.
- California habeas practitioners should note: this en banc decision applies directly to California federal habeas petitions and sets a stringent standard for using Martinez to excuse defaults in California state postconviction proceedings.
Why It Matters
Federal habeas corpus is the last resort for state prisoners who believe their constitutional rights were violated at trial. This en banc decision tightens the procedural gatekeeping that governs whether federal courts can even reach those constitutional claims. By clarifying that the Martinez exception requires a showing of a reasonable probability of a different state postconviction outcome — not just that the underlying IAC claim is substantial — the court raises the bar for California and other state prisoners seeking to have defaulted claims heard in federal court.
California has one of the largest death rows in the nation, and many capital habeas cases in the Ninth Circuit originate from California. This decision directly shapes the procedural framework within which California capital defendants pursue federal review. For postconviction defense attorneys, the ruling reinforces the critical importance of raising all viable IAC claims in state court — and of developing a full evidentiary record in state postconviction proceedings — before federal habeas is filed. Failures to do so risk procedural default that even the Martinez safety valve may not be able to cure.
